Reactive Oxygen Species (ROS)
Reactive oxygen species (ROS), such as superoxide anion (O2-), hydrogen peroxide (H2O2), and hydroxyl radical (HO•), consist of radical and non-radical oxygen species formed by the partial reduction of oxygen. Cellular ROS are generated endogenously during mitochondrial oxidative metabolism as well as in cellular response to xenobiotics, cytokines, and bacterial invasion.
ROS also activates MAPK pathways by the direct inhibition of MAPK phosphatases. Through PTEN, the PI3K pathway is subject to reversible redox regulation by ROS generated by growth factor stimulation. The activation of autophagy may be a cellular defense mechanism in response to ROS.

Beta-Sitosterol (purity>98%)
0 ImagesSynonyms: β-Sitosterol (purity>98%); 22,23-Dihydrostigmasterol (purity>98%)Beta-Sitosterol (purity>98%) is orally active. Beta-Sitosterol exhibits multiple activities, including anti-inflammatory, anticancer, antioxidant, antimicrobial, antidiabetic, antioxidant enzyme, and analgesic. Beta-Sitosterol inhibits inflammation and impaired adipogenesis in bovine mammary epithelial cells by reducing levels of ROS, TNF-α, IL-1β, and NF-κB p65 and restoring the activity of the HIF-1α/mTOR signaling pathway. Beta-Sitosterol induces apoptosis in cancer cells through ROS-mediated mitochondrial dysregulation and p53 activation. Beta-Sitosterol exerts its anticancer effects in cancer cells by activating caspase-3, caspase-8, and caspase-9, mediating PARP inactivation, MMP loss, altered Bcl-2-Bax ratio, and cytochrome c release. Beta-Sitosterol modulates macrophage polarization and reduces rheumatoid inflammation in mice. Beta-Sitosterol inhibits tumor growth in multiple mouse cancer models.
